AI Technical Summary

Technical Problem

In the control methods of thermal power units, the dynamic matching relationship between the boiler and the turbine and the measurement lag characteristics of the selective non-catalytic reduction system have not been fully considered, resulting in poor boiler-turbine coordination, untimely adjustment of ammonia injection, and delayed primary frequency regulation response, which affect the stability, economy and environmental compliance of the unit operation.

Method used

The first operating parameters are generated by the control logic optimization module, the coordination control strategy is dynamically adjusted, and the urea injection amount and primary frequency adjustment correction command are optimized by combining the control of the non-catalytic reduction system. A multi-dimensional predictive control model and neural network algorithm are used for precise control.

Benefits of technology

It has improved the stability, economy and environmental compliance of the unit operation, solved the problems of poor coordination between the boiler and turbine and untimely adjustment of ammonia injection, and improved the primary frequency regulation response speed and control accuracy.

Abstract

The invention discloses an optimization method and device of a control system, electronic equipment and a storage medium, and relates to the technical field of power system control. And the coordination control strategy is dynamically adjusted based on the first operation parameter generated through optimization so as to deal with the energy matching unbalance problem of the steam turbine and the boiler, and meanwhile, the non-catalytic reduction system is controlled by combining the first operation parameter and the second operation parameter. The problems that in an existing thermal power generating unit control method, due to the fact that traditional control and a single feedback mechanism are adopted, machine-furnace coordination is poor, the ammonia spraying amount is not adjusted in time, and primary frequency modulation response is delayed can be solved, and the technical effects of improving unit operation stability, economical efficiency and environment-friendly standard reaching capacity are achieved.
